Commercial and Industrial Energy Storage Systems: A Guide for Selection and Benefits
Commercial and industrial (C&I) energy storage systems are a key application of distributed energy storage on the user side. Their primary purpose is to leverage the price differences between peak and off-peak electricity rates to achieve investment returns, meet internal power demands, and maximize self-consumption of photovoltaic (PV) power. Additionally, they enable profit generation through peak-to-valley price arbitrage. In 2024, the market for C&I energy storage is expected to maintain rapid growth, with over 30% shipment growth predicted.
For industrial parks, factories, and other facilities planning to introduce energy storage systems, several factors must be considered to ensure optimal system selection:
Key Considerations for Industrial Energy Storage Systems
Energy Storage Technology Options:
Common C&I energy storage technologies include lithium-ion batteries, sodium-ion batteries, flow batteries, and capacitor-based storage. Each technology caters to specific energy demands, making it critical to match the technology to the application scenario.
Application Scenarios and Load Characteristics:
C&I energy storage systems are applied across various scenarios, such as microgrid storage, pure storage, distribution transformer storage, and PV storage-charging solutions. Selecting the right configuration requires an understanding of the facility’s load profile and power distribution characteristics.
Transformer Capacity and Load Data:
Before designing an energy storage system, collect data such as transformer capacity, load conditions, electricity bills for the past year, load curves, single-line electrical diagrams, and substation layouts.
Peak and Off-Peak Electricity Pricing Policies:
The profitability of C&I energy storage systems heavily depends on the difference between peak and off-peak electricity rates. Facilities in areas with significant price differences (generally over ¥0.8/kWh) benefit the most. Larger differences result in higher returns on investment.
Safety Features:
Safety is paramount. Evaluate the system’s power conversion system (PCS) features, including overcurrent, overvoltage, undervoltage, and short-circuit protection. Additionally, consider the PCS’s protection level and cooling efficiency to ensure stable operation in challenging environments.
Compatibility and Cost:
Energy storage systems integrate multiple components and technologies. Assessing PCS compatibility and overall system costs is crucial. A balanced evaluation of performance, reliability, and compatibility will aid in cost-effective decision-making.
